The event related items are usually for the previous year's. This always happens.

I don't mind it so much, because nothing essential goes on there, nothing that really gives an unfair advantage. The game is full of all kinds of different mounts, items, glamours, emotes and so on and with different ways you can acquire them. And sometimes new stuff gets added to the cash shop, which are completely optional vanity items (aside from jump potions). And without what we have on the cash shop, we have oodles of stuff we can get as vanity items.

Nothing is lost because it takes nothing away from the game nor is anything taken from what your subscription is paying for.

If instead it was a 1% drop (or general low stakes), then I'd prefer to buy it if I wanted it that badly because RNG hell can be miserable. If it's both bought and a low %age drop, people will complain that it's unfair they have to grind like hell to get something that somebody else just bought and open that can of worms.

We've just got new mounts with the last patch we can work for. At least, I don't see an issue with an item every so often being a mogstation item. It all supports the game.
